Gallring med vinkelkran : en jämförande studie av skördarkran med och utan horisontellt ledad vipparm

One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around residual trees, easing thinning work in dense stands. The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.

Vatten som väcker sinnena : - förslag för införande av vatten i Alnarps rehabiliteringsträdgård utifrån några miljöpsykologiska teorier

Theories show that water as an element, per se, increases the observer?s preference for an environment.

Finns kulturreservat utanför Sverige? : - En introduktion till bevarande av kulturhistoriskt värdefulla miljöer i utvalda europeiska länder.

This paper deals with the question of whether the symbolic language of the late Neolithic and middle Bronze Age was transferred from ceremonial monuments and barrows into the domestic sphere in the late Bronze Age. I will consider such elements as doorway orientation, the significance of boundaries and depositional practices to see if Early-Middle Iron Age settlements were indeed a major scene for ritual behaviour..

P?m?rkning vid virkesberedning - Bastning. Ett hantverksf?rs?k

This essay aims to investigate a rare method of marking up timber before hewing it. The method for marking up timber is by eyesight, where visual judgment and the use of a broad axe are the tools employed. The broad axe is driven through the bark and exposes the inner bark in a straight line. The method is described by a craftsperson dating back to the 1930s. There is a lack of information regarding the method.

Implementation av ett digitalt vågfilter på en SIC-struktur

When implementing syncronous filters with global clock nets, a substantial amount of energy is consumed in the clock net. Hence, it is interesting to reduce the size of the clock net, which in turn will reduce the total energy consumption. One way to acheive this, is to create a SIC (Structured Interfacing of Computational elements) since such a structure can be created without a global clock net. Our results show that a fifth order wavedigital filter with a sample rate of at least 10M samples/sec may be achieved.

En återvunnen och återanvänd förskola : Hur barn lär sig betydelsen av återvinning och återanvändning

This thesis means to find out how preschool teachers are working to demonstrate the importance of recycling and reuse for children. My hope is to contribute knowledge about various practical methods to establish the idea of sustainable development in the operation. I have used the method of qualitative research and done semi-structured interviews with preschool teachers on certified green flag preschools. The questions I have asked for example concerned how the preschool teachers have worked with recycling and reuse, how much the children have been able to influence and if other didactic subjects are implicated. Six interviews were made and these are summarized in the result part.
